ASH-BBIOVER.

To all whom-it may concern:

Be i known that I, RAYMOND T. Hanrarm, a citizen of the United Statesresidi a PortGarbon, in the countyof sclm iliifl and- State of Pennslvania', have -1nvented new and useful provements Ash-Removers, of whichthe following is a. specification.

This invention relates to ash removm devices for the removal ofashes-and so orth from the ash-pits of stoves, heaters, ranges andfurnaces, and it has for its main object to provide a device which mayreadily be applied to any kind or t pe of ash-pit or ash receivingchamber eit er in its on al installation or at any desired time t ere-'after.

Another object of this invention is to provide a device of the characterreferre to which will efi'ectivel remove all ashes and cinders withoutliberating any 1 portion. thereof into thecellar or other part of thehouse or surroundings to cause undesirable dust and dirt.

Still further the invention has for anobjeet to provide a device of thenature'referred to which is simple in construction, cheap tomanufacture, and easy-to'install;- and one which when in use .isexceedingly effective and cleanlyfor the purpose specified. g

With the foregoing main objects in view my' invention consistsessentially in the novel features of construction, combination andarrangements of parts hereinafter fully described and more particularlydefined by the appended claims.

In the further disclosure of the invention reference is to be had totheaccompanying sheet of explanatory drawings constituting a part of thisspecification and in which like characters of reference designate thesame. or similar parts in all the views;

Fig. 4- is a face view of the ash-box door illustrating my improved ashremover in position; and, t

Fig.- 5- is a fragmentar elevation of a slightly modified form 0 theinvention parts being broken away orin section for the sake pfclearness.

Referring more particularl to Figs. 1 to 4 of the drawings the numera 10designates a fragmentary portion of the fire-box of an ordinary kitchenstove or heater beneath which is located the ash-box 11, and 12indicates one of a series of juxtaposed fire or grate bars which areadapted for shaking to remove the ashes and cinders as hereafterexplained, and said grate bars are j ournaled in appropriate bearings13. Beneath the aforesaid grate bars 12, and located in the ash box orpit 11, I mount a conveyer casing or trough 14 which is provided at itsrear with a vertical wall 15 having .a lip 16 adapted to seat snugly ona projecting rib or flange 17 formed integral with or attached to theback wall of the ash-box 11; and at the front end of the trough 14 thereis formed a cylindrical extension18'havi a surrounding flange 19.adapted to seat on the bottom 20 of the ash-box 11, and the upperportion whereof is forwardly inclined at 21, to fit snugly to the frontthereof beneath the fire-bars 12 so that the ashes and cinder-s at thefront of the fire are pro'ected into the conveyer trough 14. Obviouslythe flange 19 is of a width to fit-snu ly transversely across theash-box. 11. Iongitudinally of the trough 14 and extension 18 there isjournalcd a hollow shaft 22, having a spiral conveyer portion 23 locatedin said. trough 14, and, in order to provide an easy means for removingthe conveyer 23, the shaft 22 is adapted to seat revolubly at itsrearend in a slotted bearing 2 1 formed in the end wall 15, flanges 25 beingprovided for preventing its accidental lon itudinal displacement. At thefront en the shaft 22, is journaled in the closed end 26, of acylindrical sleeve 27 adapted for longitudinal movement over theextension 18, and said sleeve 27 is provided with opposed longitudinalribs or projections 28 for preventi ing said sleeve 27 from axialrotation having-a working fit in correspondingly shaped notched or cutout portions 29 formed for ngso their reception in the ash-box door 30.It

is also to be noted that the closed in end 26 of the sleeve 27 seatssnugly in an opening 31, in the ash-box door 30, while at its rear endthere are provided projections or cars 32, which prevent its withdrawalfrom engagement on the extension 18 as hereafter. explained, also thereis provided on its underside an opening 33 for the purpose hereafter setforth.

The hollow shaft 22, is formed at its for Ward end with an internallysquared portion 34 to receive the elongated and correspondingly. shapedend 35, of a shaker crank 36 provided with a handle 37 and it is to behere remarked that the forward ends of the fire bars 12 arecorrespondingly cored out at 38 so that the said shaker crank 36 servesthe dual purposes of manipulating the conveyer 23 as well as for removinthe ashes and cinders from the firebox 10 y shaking the grate bars 12.

In the slightly modified form of-the invention shown in Fig. 5, thedevice is shown asattached beneath the bottom of the ash box 11, and.wlth the extension of the cons veyertrough 14 projecting flush with thesurface of the skirting flange 39, a pail or bucket 40 being alsoindicated for receiving the ashes-and so forth when they are to beremoved from the ash-box and emptied or stored away. i

The operation of my improvedv ash remover is'briefly as follows. Whenthe fire is.: to be shaken down the crank 36 is inserted in the coredout part 38 of the fire bar 12v andmanipulated. in the wellknown way,which results in the ashes falling'into the conveyer trough 14s. Thecylindrical sleeve 27 is. thereupon drawn out into extended:position-asby a knob 41 Fig. 1-'- relative to.the-cylindrical extension18and thecrank 36- insertedinto operative connection with thevhollow"shaft? 22, it being noted that thesquared part 35. is long-enou h t'o'permit this connection when the parts'2 --18 arethus extended. Byrotating the crank 36" the spiral conveyor. 23 willdraw the ashesforward; through the extension 18 into-the extended sleeve 27 fromwhence they will be discharged through the aperture 33 into the pail orreceptacle 40. When the receptacle or pail 40 is full it can be'removedfor emptying after the sleeve 27 has'been pushed into-collapsed positionrelative to the extension 18.

From the foregoin description it will. be

readily understood t at by my invention I provide an ash remover whichcan be readily built into any of the standard types of stoves, heaters,rangesand furnaces at the time of. manufacture and installation, or itmay be made separate and inserted thereafter. Obviously when the deviceis built into new stoves, heaters, furnaces and ranges the bottom of theash box ll-may be inclined downwardly from all sides to the trough 14.-so that as the ashes are fed forward when the conveyor 23 is rotated thefollowing ashes will all have a gravity feed or fall into the saidtrough14; while at the same time the inclined parts will prevent any cloggingof the ashes in the extension 18.

Eurthermore it will be obvious that by placieriig a cloth over thesleeve 27-when extend --and pail 41) all tendency of dust to escape whenthe device is in use will be prevented, while the entire operation canbe effected without-opening the ash-box door 30.

Although I have described'one practical embodiment of the invention itwill be readily understood'that' the Various details of constructionshown maybe altered and changed to accommodate difierent servicerequirements without departing from the spirit and sec e'of' the saidinvention and as defined b t (e appended-claims.
